SRX5400 Services Gateway Craft Interface Alarm LEDs and Alarm Cutoff/Lamp Test
Button
Two large alarm LEDs are located at the upper right of the craft interface. The circular
red LED lights to indicate a major alarm condition that can result in a system shutdown.
The triangular yellow LED lights to indicate a less severe minor alarm condition that
requires monitoring or maintenance. Both LEDs can be lit simultaneously. A condition
that causes an LED to light also activates the corresponding alarm relay contact on the
craft interface.
To deactivate the major and minor alarms, press the button labeled ACO/LT (for “alarm
cutoff/lamp test”), which is located to the right of the alarm LEDs. Deactivating an alarm
turns off both LEDs and deactivates the device attached to the corresponding alarm
relay contact on the craft interface.
Table 5 on page 19 describes the alarm LEDs and alarm cutoff button in more detail.
